Canada Requirements Only (continued)  
Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or  
alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications  
company cause to request the user to disconnect the equipment.  
Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines  
and internal metallic water pipe system, if present, are connected together. This precaution may be particularly  
important in rural areas.  
Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric  
inspection authority, or electrician, as appropriate.  
Notice: For equipment using loopstart lines, please note that the Ringer Equivalence Number (REN) assigned to each  
terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone  
interface. The termination on an interface may consist of any combination of devices subject only to the requirement  
that the sum of the Ringer Equivalence Numbers of all the devices does not exceed 5. The REN is located on the FCC  
Rules Part 68label located on the bracket of the module, or on the back of the unit.  
Canada CS-03 -- Règles et règlements  
Avis: L'étiquette d'Industrie Canada identifie le matériel homologué. Cette étiquette certifie que le matériel est  
conforme aux normes de protection, d'exploitation et de sécurité des réseaux de télécommunications, comme le  
prescrivent les documents concernant les exigences techniques relatives au matériel terminal. Le Ministère n'assure  
toutefois pas que le matériel fonctionnera à la satisfaction de l'utilisateur.  
Avant d'installer ce matériel, l'utilisateur doit s'assurer qu'il est permis de le raccorder aux installations de l'entreprise  
locale de télécommunication. Le matériel doit également être installé en suivant une méthode acceptée de  
raccordement. L'abonné ne doit pas oublier qu'il est possible que la conformité aux conditions énoncées ci-dessus  
n'empêche pas la dégradation du service dans certaines situations.  
Les réparations de matériel homologué doivent être coordonnées par un représentant désigné par le fournisseur.  
L'entreprise de télécommunications peut demander à l'utilisateur de débrancher un appareil à la suite de réparations ou  
de modifications effectuées par l'utilisateur ou à cause de mauvais fonctionnement.  
Pour sa propre protection, l'utilisateur doit s'assurer que tous les fils de mise à la terre de la source d'énergie électrique,  
des lignes téléphoniques et des canalisations d'eau métalliques, s'il y en a, sont raccordés ensemble. Cette précaution  
est particulièrement importante dans les régions rurales.  
Avertissement: L'utilisateur ne doit pas tenter de faire ces raccordements lui-même; il doit avoir recours à un service  
d'inspection des installations électriques, ou à un électricien, selon le cas.  
Avis: Veuillez prendre note que pour tout appareillage supportant des lignes de type loopstart,l'indice d'équivalence  
de la sonnerie (IES) assigné à chaque dispositif terminal indique le nombre maximal de terminaux qui peuvent être  
raccordés à une interface. La terminaison d'une interface téléphonique peut consister en une combinaison de quelques  
dispositifs, à la seule condition que la somme d'indices d'équivalence de la sonnerie de tous les dispositifs n'excède pas

Installing and Operating Passport ARN Routers  
Additional Equipment  
To install the ARN, you may need some additional items that are not part of the  
ARN accessory package. Before installing the ARN hardware, ensure that you  
obtain all the cables, tools, and other equipment that you need.  
Cables  
Unless they were specifically ordered, the cables necessary for your network  
configuration are not part of the ARN accessory package. If you do not have the  
proper cables, contact your network administrator or see the Cable Guide.  
Management Console  
You can attach an optional computer terminal or PC as a console to the ARN to  
monitor the results of startup diagnostics and perform manual boot configurations.  
Or you can attach any AT-compatible modem to allow remote dial-in access to  
diagnostics and configuration.  
Note: To use the Netboot, Directed Netboot, or Local Boot options for booting  
and configuring the ARN (see Chapter 3, Operating the ARN), you must  
have a local terminal connected the first time the ARN powers up.  
Mounting Hardware  
To rack-mount the ARN, you need a Phillips screwdriver and an electronic  
enclosure rack that meets the following specifications:  
Heavy-duty steel construction  
Electronic Industries Association (EIA) standard hole-spacing  
Width of 19 in. (48.26 cm) and depth of 24 in. (60.96 cm)  
If the rack does not have threaded rail holes, you must use cage nuts (see  
Figure 1-1) to use with the cagenut screws.

Installing the ARN  
Verifying Site Requirements  
The installation site must provide a certain amount of free space around the ARN  
to dissipate heat, as detailed in Table 1-1.  
Table 1-1.  
Installation Space Requirements  
Width  
Depth (minimum)  
Depth (for servicing)  
22.5 in. (57.2 cm)  
15 in. (38.1 cm)  
25 in. (63.5 cm)  
In addition, the installation site must meet the electrical and environmental  
specifications listed in Appendix C.  
Caution: You must use grounded electrical power outlets with the ARN.  
Installing the ARN  
When you are ready to install the ARN in its final location, you have two options:  
Position the ARN on a flat, sturdy, horizontal surface.  
Mount the ARN in an electronic enclosure rack.  
Positioning the ARN on a Flat Surface  
When positioning the ARN on a flat surface, make sure that the surface is:  
Large enough for the ARN to operate properly (Table 1-1)  
Sturdy enough to support the combined weight of the ARN and any cables  
that you connect  
You should place the self-adhesive, rubber feet (shipped with the ARN) on the  
bottom of the ARN chassis. These feet not only protect the surface on which you  
position the ARN, they provide added friction against the weight of any cables  
that you attach to the device.

Installing and Operating Passport ARN Routers  
Rack-Mounting the ARN  
For this procedure, you need:  
Two flange brackets and eight #6 Phillips screws (shipped with the ARN)  
A Phillips screwdriver  
An electronic enclosure rack. If the rack does not have threaded rail holes, you  
must attach the four cage nuts shipped with the ARN.  
Four #10 cagenut screws and washers (shipped with the ARN)  
To rack-mount the ARN:  
1. Determine how you want the ARN to fit in the equipment rack.  
Multiple holes in the flange brackets provide several options for  
rack-mounting the ARN. How you attach the flange brackets determines how  
far the router extends outside or remains inside the rack. Figure 1-2 shows  
three of the most common locations for the brackets.  
2. Attach a flange bracket to each side of the ARN.  
a. Align four bracket holes with four holes in the ARN enclosure  
(Figure 1-2).  
b. Insert a #6 Phillips screw through each hole and into the ARN.  
c. Tighten the four screws with a Phillips screwdriver.

ARN Module Locations  
The ARN is available in the following base module configurations:  
One Ethernet AUI and Ethernet 10BASE-T interface  
One Ethernet 10/100BASE-Tx interface  
One Ethernet 100BASE-Fx interface  
One Token Ring interface (STP only)  
ARN expansion modules provide additional Ethernet (AUI and 10BASE-T), token  
ring (STP and UTP), and serial interfaces. Each ARN WAN adapter module adds  
one serial, ISDN BRI, V.34 modem, T1/FT1, E1/ET1, 56/64K DSU/CSU, or X.25  
PAD interface.  
The Ethernet base and expansion modules can also contain an optional data  
collection module (DCM). This optional DCM gathers Ethernet statistics for a  
remote monitoring (RMON) utility. A subset of these statistics is gathered with a  
built-in RMON function on the Ethernet10/100BASE-Tx and -Fx interfaces. See  
Configuring RMON and RMON2 on BayRS Routers for information about how to  
enable and use each RMON data collection implementation.

Connecting Communications Cables  
Gather the communications equipment and cabling that you will attach to the  
ARN. If you do not have the proper cables, contact your network administrator or  
see the Cable Guide.  
Note: For cable interface descriptions, see Appendix C.  
Then, complete the steps in the applicable sections:

Connecting to an Ethernet Interface  
You can connect an Ethernet cable to any ARN base or expansion module that  
contains an Ethernet interface option.  
Note: On Ethernet modules that offer two interface types -- an attachment unit  
interface (AUI) transceiver interface or a UTP interface -- you can only use one  
interface at a time. For example, you can connect to either the AUI transceiver  
interface or the 10BASE-T UTP interface on the base module, but you cannot  
use both interfaces at the same time.

Installing the ARN  
Connecting to the AUI  
The AUI interface provides broadband, baseband, fiber, and shielded twisted pair  
(STP) support, depending on the transceiver and cables you use.  
Caution: Connecting the ARN AUI interface directly to the AUI interface on  
an Ethernet station violates IEEE 802.3 standards. The AUI interface is  
designed only for connection to a transceiver.  
To attach an Ethernet AUI transceiver (drop) cable to the AUI connector on an  
Ethernet module:  
1. Connect an Ethernet AUI drop cable to the interface labeled AUI  
(Figure 1-5).  
The cable must have a 15-position D-SUB receptacle.

Connecting to a Token Ring Interface  
You can connect a token ring cable to any ARN base module or expansion module  
that contains a token ring interface option. Each of these interface options offers  
two token ring interface types: an STP interface or a UTP interface.  
Note: You can use only one token ring interface on an ARN base or expansion  
module at any time. For example, you can connect to either the STP interface  
or the UTP interface on a base module, but you cannot use both interfaces at  
the same time.

Understanding the Startup Process  
To operate, the ARN requires two files: a software image and a configuration file.  
Each time you start the ARN, it completes a process to load these files.  
The software image contains a group of executable files that support the  
protocols that the network requires. The ARN uses the software image called  
arn.exe. The process of obtaining and using this image is called booting.  
To bridge and route traffic, the ARN also needs a configuration file that is  
tailored to the network. A configuration file is a binary system file that  
contains hardware and software configuration data. The default configuration  
file is named config.  
Nortel Networks ships the executable and default configuration files on a  
PCMCIA flash card, but the ARN can also obtain them over the network. Getting  
a file over the network is called network booting, or netbooting. Getting a file  
from the router file system, stored in flash memory, is local booting.

Installing and Operating Passport ARN Routers  
When you start the ARN for the first time, it completes an initial startup procedure  
to boot and connect to the network using either a default configuration file or one  
already customized and available on the network.  
You use one of four boot options to complete the initial software startup. Table 2-1  
summarizes the four options; the sections that follow provide steps for completing  
each option.

You may not be able to use all methods described in this chapter to boot over some  
interfaces on your router. For example, you cannot netboot over an FT1/T1  
interface. In some cases, you may use one interface to boot your router and then  
switch to a different interface (such as the FT1/T1 DSU/CSU) to establish your  
initial IP network connection to the management workstation.

Installing and Operating Passport ARN Routers  
Starting the ARN for the First Time  
The ARN factory defaults are set to find the image file and configuration file from  
the following locations:  
Image file -- on the local PCMCIA flash memory card  
Configuration file -- over the network  
These default settings work with the default EZ-Install procedure.  
The first time you power on an ARN, the router steps through its diagnostic tests  
and then attempts to boot over all of its serial (COM) interfaces using EZ-Install.  
Note: Coordinate the initial startup of the ARN with your network  
administrator. To determine which software configuration option is best for  
your site and for instructions on setting up a boot server, the network  
administrator can refer to Configuring Passport Remote Access.  
If your network administrator has configured the network for the EZ-Install  
procedure, the router boots using its local image and obtains its configuration file  
over the network. Your network administrator can then connect to the ARN and  
manage it remotely. For more information, refer to the next section, Using  
If your network administrator does not configure the network for EZ-Install, the  
ARN cannot obtain its configuration file from the network, and the EZ-Install  
procedure fails. The ARN then attempts to boot locally with the configuration file  
that resides on its flash memory card. Refer to Using Netboot, Directed Netboot,  
or Local Bootfor more information.  
If both the EZ-Install and local boot attempts fail, the EZ-Install and local boot  
processes repeat until one of the following occurs:  
The ARN boots successfully.  
You interrupt the boot process to enter the ARN monitor.  
You turn off the ARN.  
The following sections describe how to use each of the different boot options for  
the ARN.

Starting the ARN  
Using EZ-Install  
EZ-Install is the default installation option provided by Nortel Networks. This  
option requires that your network administrator has set up the network so that you  
Install a flash memory card.  
For instructions, see Installing the Flash Memory Cardon page 1-31.  
Connect at least one serial (COM) interface to the network.  
For instructions, see Connecting Communications Cableson page 1-10.  
Note: If your ARN does not have a COM interface, you must configure the  
ARN using one of the other methods such as netboot or directed netboot over  
an Ethernet or token ring interface. Or, you may local boot the ARN and run  
the Quick-Start script. For more information, see Using Netboot, Directed  
Netboot, or Local Booton page 2-6.  
To use EZ-Install:  
1. Press the power switch on the ARN back panel to the ON position.  
The ARN comes on and activates EZ-Install.  
Note: If you power on the ARN before the network administrator is ready,  
restart the ARN by pressing the reset button on the rear panel. See Chapter 3,  
Operating the ARNfor more information on resetting the ARN.  
2. Ensure that the ARN boots correctly.  
When the ARN boots, its LEDs flash in a particular order. For information on  
checking the ARN front-panel LEDs to ensure that the installation was  
successful, see Understanding the ARN LEDson page 3-1.

Installing and Operating Passport ARN Routers  
Using Netboot, Directed Netboot, or Local Boot  
When you netboot or local boot the ARN, you must use a command line interface  
that accesses the router software. To use a command line interface, you can:  
Wait for the ARN to local boot (that is, wait for the router to fail EZ-Install  
and then attempt to boot using its local configuration file). After the ARN  
boots locally, you can log in to the Technician Interface and redefine the boot  
process.  
Interrupt the boot process using a break sequence and log in to the ARN  
monitor to redefine the boot process.  
Using the netboot, directed netboot, or local boot options requires that you:  
Connect any necessary communications cables to access the network.  
Connect a management console.  
Connect the ARN power cable.  
Install a flash memory card.  
See Chapter 1, Installing the ARNfor instructions on how to complete these  
tasks.  
Interrupting the Boot Process  
ARN monitor allows you to bypass the EZ-Install procedure.  
Note: Before you power on the ARN, make sure that you have installed the  
router and connected the management console equipment you need (see  
Connecting a Management Consoleon page 1-23).  
To interrupt the boot process:  
1. Press the power switch on the ARN back panel to the On position.  
As the router powers on, your console displays the ARN diagnostic tests.  
After successfully completing these tests, the router begins the EZ-Install  
procedure and attempts to boot over the network.

2. While the router is running the EZ-Install procedure, issue a break  
sequence from the management console.  
The ARN monitor login prompt appears.  
Note: Be sure to issue a break sequence before the boot process completes.  
Break sequences can vary, depending on the console type. Some management  
consoles have specific Breakkeys on their keyboards; other require a key  
sequence to issue a break (for example, Cntrl-C or ~ #). For the break sequence  
for your management console, see the PC/terminal documentation.

Continuing with Netboot  
Note: Continuing with the netboot option requires that you have already  
logged in to either the ARN monitor or Technician Interface command line  
software. For instructions, see Logging in to the Command Line Softwareon  
page 2-7.  
To use the netboot option, you must have at least one serial, Ethernet, or token ring  
interface connected to the network. Before you start the netboot procedure, ask  
your network administrator to:  
Verify that the network is set up for the netboot procedure, as described in the  
Configuring Remote Access for AN and Passport ARN Routers guide.  
Provide you with the parameter arguments to the interface configuration  
command ifconfig you will use in Step 4.  
The ifconfig command configures the parameters necessary to load the  
software image file and configuration file from a remote server over the  
network.  
Note: Keep a record of the complete ifconfig command, because you need it  
for future reference.  
You can use the ARN monitor, Technician Interface, or Site Manager to perform  
netboot. However, this guide assumes that you are using either the ARN monitor  
or the Technician Interface.  
To use the netboot option:  
1. At the command line prompt, enter the ifconfig command provided to  
you by your network administrator and press the Return key.  
The following is a sample command:  
ifconfig com1 9.0.0.2 255.0.0.0 9.0.0.3  
For more information about the ifconfig command, see Using the ifconfig  
Commandon page A-2.  
2. Enter the following command and press the Return key to verify the  
configuration you specified in Step 1:

Starting the ARN  
The getcfg command shows the source location, either local or network, of  
the boot image file and the network configuration file. It also shows the  
interface configuration settings that you specified using the ifconfig  
command.  
If getcfg displays the correct information, continue to the next step.  
Otherwise, reenter the correct ifconfig command. If you need assistance,  
contact your network administrator.  
3. Enter the following command and press the Return key to boot the ARN:  
boot  
Your console displays messages indicating the progress of the netboot  
procedure.  
Note: If the ARN cannot find a software image file or a configuration file  
using the netboot procedure, it attempts to local boot once. If both attempts  
fail, the ARN continues to netboot and local boot until it boots successfully. If  
the ARN remains in this loop, follow the steps in Interrupting the Boot  
Processon page 2-6.  
4. Ensure that the ARN boots correctly and successfully connects to the  
network.  
When the ARN boots, its LEDs flash in a particular order. To ensure that the  
installation was successful, see Ensuring a Successful Installationon  
page 3-9.  
Contact your network administrator to verify that the ARN is now connected  
to the network. Your network administrator can refer to Configuring Passport  
Remote Access to troubleshoot any problems.

Ensuring a Successful Installation  
After connecting the ARN to the network, you can ensure a successful installation  
by checking the diagnostic LEDs on the front panel of the base module (refer to  
Figure 3-1 on page 3-2).  
When you power on the ARN, the following sequence of front panel LED activity  
should occur:  
All base module LEDs light momentarily; this tests that the LEDs are  
operational.  
The Run, Boot, and Fail LEDs count through a short, initial startup sequence.  
The Pwr (power) LED lights and remains on.  
The Run LED begins flashing and continues to flash until the ARN completes  
all diagnostic tests.  
As the diagnostic procedure tests each module, the LED representing that  
module flashes slowly. If the module passes its diagnostic test, the LED  
remains on. If the module fails its diagnostic test, the Fail LED remains on  
and the module LED flashes rapidly.  
After completing the diagnostic testing procedure, the boot process begins.  
The Run and Boot LEDs indicate the boot status as shown in Table 3-15.

If the LEDs on the ARN light in this sequence, your installation is successful.  
Contact your network administrator to verify that the ARN is now connected to  
the network.  
If the LEDs do not light in this sequence, your network administrator can refer to  
Configuring Remote Access for AN and Passport ARN Routers to help  
troubleshoot the problem.  
Note: If the ARN does not contain an expansion module, an adapter module, a  
redundant power supply, a data collection module, or a flash card, the LEDs  
associated with these components remain off.  
If you need additional assistance, contact your local Nortel Networks Technical  
Solutions Center.

Installing and Operating Passport ARN Routers  
Downloading New Boot and Diagnostic Code  
When installating an adapter module as an upgrade to your existing hardware  
configuration, you must verify that the ARN contains the minimum required  
version of programmable read-only memory (PROM) code for the module you are  
installing. BayRS release media includes the latest boot and diagnostic code at the  
time it is shipped, but if your upgrade requires newer code, you must manually  
download it to the router PROM.  
To determine which version of boot and diagnostic code you need when installing  
a particular adapter module, see see the module-specific Supplement that ships  
with the module, and to the Document Change Notice or the Release Notes  
distributed with your BayRS release. For instructions on how to upgrade the  
PROM code in flash memory, refer to the Upgrading Routers guide.  
Powering Down  
Before installing a WAN adapter module:  
1. Turn off the ARN.  
Set the power switch to 0, off (refer to Figure 1-25 on page 1-30).  
Warning: You cannot hot-swap ARN WAN adapter modules.  
2. If present, turn off or disconnect the redundant power supply.  
3. Attach an antistatic wrist strap.  
Caution: Electrostatic discharge can damage hardware. You must wear the  
antistatic wrist strap whenever you handle printed circuit boards.  
You receive an antistatic wrist strap with the adapter module. See the  
instructions included with the wrist strap.  
The wrist strap directs static electricity from your body to the router chassis,  
preventing discharge to sensitive electronic components.

Installing and Operating Passport ARN Routers  
Using the ifconfig Command  
A router interface cannot communicate in an IP network without an IP address.  
Because an ARN netboots over one of its serial, 56/64K DSU/CSU, Ethernet, or  
token ring links, the netboot interface must have a valid IP address.  
You use the interface configuration command ifconfig to do the following:  
Configure the routers initial IP interface to the network. (The initial IP  
interface should be a serial interface if you are using EZ-Install.) You also use  
the same procedure to configure other serial interfaces for the netbooting  
procedure.  
Configure Ethernet or token ring interfaces for the netbooting procedure.  
Enable or disable netbooting on an interface.  
Configuring an IP Serial or 56/64K DSU/CSU Interface for Netbooting  
Configure a serial or 56/64K DSU/CSU (COM) interface to the IP network using  
the following interface configuration command:  
ifconfig [<synchronous_options>] <interface> [<IP_address> <subnet_mask>  
[<next_hop_address>]]  
The synchronous options variable indicates some combination of the following  
settings:  
[-d | -r [56 | 64] | -fr [-annexd | -lmi | -annexa] | -int_clk]  
Note: Make sure to separate command options with spaces.

Configuring the ARN for Netboot and Directed Netboot  
Using the bconfig Command  
You use the bconfig command to configure the boot option.  
To use netboot, you use the boot configuration command bconfig to specify  
that the ARN software image file or configuration file resides on the network.  
To use directed netboot, you use the bconfig command to specify the IP  
address of the server and the full pathname to the software image and  
configuration file.  
To use local boot, you use the bconfig command to specify that the  
configuration file and software image both reside on the local file system (that  
is, the PCMCIA Flash card).  
Format for the bconfig Command  
To configure an interface for netboot, use the following format:  
bconfig -d [image | config]  
To configure an interface for directed netboot, use the following format:  
bconfig [image | config] [local | network [<TFTP_host> <TFTP_pathname>]]  
You must use the bconfig command twice: once to specify the location of the  
software image, and again to specify the location of the configuration file.  
Refer to Table A-5 for a complete description of the bconfig command.

some other management tool to fully customize your routers configuration.)  
To start the ARN on the network using Quick-Start, you run the inst_arn.bat script  
and enter information at the prompts. The ARN automatically selects options for  
some prompts, and you can accept default values for many of the other prompts.

Installing and Operating Passport ARN Routers  
Before You Run Quick-Start  
To aid you in answering Quick-Start prompts, some sample worksheets are  
provided. Fill them out with assistance from your network administrator. The  
worksheets contain options that appear at each prompt when configuring a serial  
interface, and space for you to enter your own information. If you are configuring  
an interface other than the serial interface, the prompts will differ from what is  
guide and review the actual Quick-Start prompts and options carefully before  
replying.  
Be sure to fill out the worksheets and read all sections of this appendix before you  
run the Quick-Start script. The sections in this appendix, Filling Out the  
Worksheetsand Running the Quick-Start Script,provide additional  
information about the Quick-Start script.  
Note: Contact your network administrator for assistance in selecting  
worksheet responses.  
Understanding Quick-Start Connector Names and Numbers  
The Quick-Start script assigns a name and number to each interface, depending on  
its location on the ARN.  
In addition to either an Ethernet or token ring base module, the ARN can contain  
expansion modules and adapter modules (Figure B-1).

Filling Out the Worksheets  
The inst_arn.bat script provides many options for configuring the ARN on a  
network. Since typical remote access uses a serial interface over a wide area  
connection, this sample describes only the options involved with a serial  
configuration.  
Note: This section provides worksheets only for a serial interface  
configuration over a wide area connection. It does not contain worksheets for  
LAN configuration options. If configuring a LAN interface, read the  
Quick-Start text and prompts carefully before responding, as they will differ  
from the serial sample.  
We suggest the following procedure when you fill out worksheets:  
1. Fill out the Global Information Worksheet completely.  
The sample worksheet lists options common to all serial interface  
configurations.  
2. After you record your protocol selections on the Global Information  
Worksheet, fill out one Router Protocol worksheet.  
114200-E Rev 00

Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Installing and Operating Passport ARN Routers  
This worksheet lists specific options for RIP, OSPF, or Static Route  
configurations. For example, if you select RIP as your routing protocol, you  
need to fill out only the worksheet pertaining to RIP.  
3. Fill out one Wide Area Protocol worksheet.  
This worksheet lists specific options for Nortel Networks (proprietary)  
Point-to-Point Protocol (PPP), frame relay, Standard PPP, and switched  
multimegabit data service (SMDS) configurations. For example, if you select  
frame relay as your wide area protocol, you need to fill out only the frame  
relay worksheet.  
4. Run inst_arn.bat as described in Running the Quick-Start Scripton  
page B-16.  
Or, a remote-site operator runs the installation script as described in this  
guide.  
5. When the router has an initial connection to the network, use the guide  
Configuring Remote Access for AN and Passport ARN Routerse to  
configure the router using Site Manager.

ARN Technical Specifications  
Hardware Communications Options  
The ARN is designed to scale to your needs. In addition to either an Ethernet or  
token ring base module, you can add an optional expansion and up to two optional  
adapter modules to the ARN.  
The ARN is available in the following base module configurations:  
One Ethernet AUI and Ethernet 10BASE-T interface  
One Ethernet 10/100BASE-Tx interface  
One Ethernet 100BASE-Fx interface  
One Token Ring interface (STP only)  
The ARN supports the following expansion modules:  
One Ethernet AUI and Ethernet 10BASE-T interface  
One token ring media access unit interface (STP and UTP option)  
Three serial interfaces  
One Ethernet AUI and Ethernet 10BASE-T interface and three serial  
interfaces  
One token ring interface (STP and UTP option) and three serial interfaces  
Note: The Ethernet AUI and 10BASE-T base and expansion modules can also  
contain an optional data collection module (DCM). This optional DCM  
gathers Ethernet statistics for a remote monitoring (RMON) utility. A subset of  
these statistics is gathered with a built-in RMON function on the  
Ethernet10/100BASE-Tx and -Fx interfaces. If your router has both types of  
RMON data collection installed, you can run the built-in RMON function or  
the optional DCM module, but not both at the same time. If you have one  
configured, the other is shut off. Your network administrator can refer to  
Configuring RMON and RMON2 on BayRS Routers for additional information  
about how to enable and use each RMON data collection implementation.  
Check also the Documentation Change Notice and Release Notes for related  
information.  
The ARN also supports up to two of the following adapter modules:  
One serial interface  
One ISDN BRI S/T interface

Interface  
Description  
Ethernet and  
Supports the Ethernet and IEEE 802.3 standards that provide LAN connectivity. The  
Second Ethernet ARN can have up to two Ethernet interfaces: one on the base module and one on an  
expansion module.  
The Ethernet interface on the base module can be a 10BASE-T, a 10/100BASE-Tx, or a  
100BASE-Fx. The 10BASE-T can also be used as an expansion module. There are two  
ports available for each 10BASE-T: a 10BASE-T and an 802.3 AUI port; however, you  
can use only one of these ports (10BASE-T or AUI) on each module at a time.  
The 10BASE-T and 10/100BASE-Tx interfaces provide unshielded twisted-pair  
support; the 10BASE-T AUI interface provides broadband, baseband, fiber, and  
shielded twisted-pair support, depending on the transceiver and cabling you use. The  
100BASE-Fx provides fiber support.  
Token Ring and  
Second Token  
Ring  
Supports the token ring and IEEE 802.5 standards that provide LAN connectivity. The  
ARN can have up to two token ring interfaces: one on the base module and one on an  
expansion module.  
The token ring base module supports a 9-pin (DB-9) STP token ring interface. The  
token ring expansion module supports both a 9-pin (DB-9) STP connector and a UTP  
connector; however, you can use only one port (STP or UTP) on the expansion module  
at a time.  
Both token ring connector types support the 802.5 media access control (MAC)  
token-passing protocol, the 802.2 Type 1 (connectionless) protocol, the 802.2 Type 2  
(connection-oriented) protocol, and the 16-Mb/s Early Token Release (ETR) protocol  
over the appropriate cabling.

Description  
Serial  
Provides WAN connectivity. ARN models can have up to five serial ports (three on an  
expansion module and up to two adapter modules).  
Each port can operate independently with RS-232, RS-422, RS-449, RS-530, V.28,  
V.35, and X.21 cables. Serial capability allows internal or external clocking.  
ISDN BRI  
Supports an S/T or U interface. The BRI provides two B channels, and supports full  
D-channel signaling and call setup/tear-down as defined in 1988 CCITT (now ITU-T)  
Q.921 and Q.931. For more information on ISDN, functional groups, or reference  
points, refer to Configuring Dial Services.  
The ISDN BRI option is available as an adapter module for any ARN model.

FT1/T1 and  
Provides an interface to convert incoming packet data from an external T1 or E1 line  
FE1/E1 DSU/CSU (using an RJ-48C connector). Because the interface integrates the Channel Service  
Unit (CSU) function on each T1 or E1 port, it allows direct connection to the network. A  
T1 port can transmit or receive a total of 24 DSO HDLC channels for each DS1 frame.  
X.25 PAD  
Provides an X.25 PAD interface.  
Provides a V.34 modem interface.

Requirements for European Operation  
Power Requirements for ISDN BRI and Serial Adapter  
Modules  
The ISDN BRI and serial adapter modules obtain power from the host chassis and  
have the power requirements shown in Table D-14.  
Table D-14.  
Voltage  
ISDN BRI Power Requirements  
Amperage  
+5 V  
1 A  
+12 V  
-12 V  
0.15 A  
0.15 A  
The power drawn from the host chassis combined with that required for any other  
cards and accessories must be within the power rating of the host chassis.  
When you install an ISDN BRI or serial adapter module in an ARN, make sure  
that you do not impair the integrity of the network protection from hazardous  
voltages used or generated internally by the host chassis.  
Clearance and Creepage Distances for ISDN BRI and Serial  
Adapter Modules  
The clearance and creepage distances (shown as X and Y, respectively, in  
Figure D-7 and Table D-15) must be maintained between the card and:  
The host chassis in which it is installed  
Any adjacent cards installed in the host chassis  
The exception to this rule is the edge connector, which resides in the host chassis  
backplane, where no minimum distance applies.

Requirements for European Operation  
The creepage distances apply to the normal office environment. When the local  
environment within the host chassis is subject to conductive pollution or dry  
nonconductive pollution that could become conductive due to condensation, the  
creepage distances shown in parentheses in Table D-15 apply.  
The clearance and creepage distance between adjacent points should be checked  
as follows:  
The clearance distance (X) is the shortest distance between two points  
measured through the air.  
The creepage distance (Y) is the shortest distance between two points  
measured across a surface.  
If in doubt about calculating these distances, obtain advice from a competent  
telecommunications safety engineer. Failure to install the ISDN BRI or serial  
adapter module according to these instructions invalidates the conditions of the  
BABT General Approval agreement.
